        After you replace that recap the Psu if it uses Samwha Wb and Wl caps. Maybe add a fan to X and Ysus heatsinks.

                It's always better to include the picture on this site so that anyone else looking at a similar fault can see it.

                    disconnect one of the buffer boards and see if you get half a picture

                        A funny fuse story – Lumix LX100 II
                        by corrize
                        Hello, I disassembled this dead camera, and found this WTF… Two fuses soldered one above the other !
                        I was pretty sure nobody touched it before, but that can't be from factory. There is flux, and capacitor is probably missing.
                        The other weird thing : the fuses are « G » fuse : (0.75A – 8V), seems very low. The original fuse should be « O » : (32V 2,5A).
                        There is « O » mark beside. All fuses have the same mark letter on main board. So, I can deduce it's a « O » fuse.
                        And this correspond to the issus I saw : when I plug the battery, I measure the voltage dropping...

                        Samsung UE46ES8000 Blown fuse but no other signs of short
                        by jesterace
                        Hi I wonder if anyone might be able to steer me in the right direction. I have this Samsung UE46ES8000 TV and it went bang during use. The main fuse on the PSU board is open. I've checked every diode/mosfet/transistor I can see and nothing appears to be short to cause the fuse to go. The DC output of the bridge rectifier is not short either. I've seen online that some of these models are known for having their PFC mosfet or other mosfets shorting and blowing the fuse but i'm not seeing that here. If anyone aware of these models having any issues to cause this? I'm reluctant to just replace the...

                        Help replacing fuse on my Mimaki CJV300-160 vinyl printer
                        by jshhh
                        Hi guys,

                        I'm inexperienced with electronics repairs, I've done a little bit of soldering caps and whatnot, but i have a blown fuse on this mimaki printer I got which I have bought a replacement for.

                        How do I remove this type of fuse (see picture)...it kinda looks like it would pull out of that bracket but it didn't come at first pull and I didn't want to brute force it incase it's soldered on there like most of the rest of the components.

                        Anybody know how to remove this type of fuse?

                        (The fuse is toward the bottom of the image labeled F2)...

                        Argon SA1 audio amplifier power-supply - fuse blown after fixing the short?
                        by Babbar
                        I found a project in the electronics trash yesterday. A nice Argon SA1 audio amp with some electrical issue. Took it apart and saw that the 4A250V fuse was blown so started lifting components to find the short. Eventually got to two MOSFETs (model FTA14N50C) that are shorted and when i took them out the short was gone.

                        Now i didn't have any replacements of the same model of course but i found a couple with pretty similar spec i thought (K10A60D & K12A50D) and put them in. Also replaced the blown fuse with a 3.5A250V one. Checked another time for short circuit and plugged it in....

                        Matsui 175S microwave fuse replacement
                        by drykid
                        Hi,

                        I recently picked up a used Matsui 175S microwave that was powering up (starts, turntable rotates) but not heating. From looking online the most likely culprit was the fuse, but unfortunately in this one the fuse had heated up and fused with the (badly designed) fuse holder and couldn't be removed. I guess this might indicate further issues beyond the fuse itself but at this stage I just want to replace the fuse and see how I go from there.

                        Anyway since I couldn't get out the fuse itself the easiest fix was to replace the fuse holder assembly that runs between the...
